As the global beverage market pivots toward sustainable PET solutions and "ready-to-drink" (RTD) convenience, the demand for precision double seaming has reached an all-time high. Manufacturers are no longer just looking for closure; they are seeking hermetic integrity that ensures zero leakage and maximum flavor retention.
Modern Double Seamer Machines utilize a two-stage process: the first operation forms the cover hook around the body hook, while the second operation flattens the seam to create a mechanical bond. This is critical for PET cans where the material properties differ from traditional aluminum.
With the rise of Circular Economy initiatives, double seamers now accommodate thinner gauges and recycled PET (rPET). Our technology ensures that even with material optimization, the structural integrity of the can remains uncompromised during high-speed production cycles.
Established in 2021, Shanghai COPAK Industry Co., Ltd. maintains a strategic sales office in Shanghai and a state-of-the-art production facility in Guangdong Province. As a premier provider of eco-friendly packaging solutions, we specialize in bridging the gap between innovative design and industrial feasibility.
Our portfolio—ranging from 1oz to 32oz—includes PET cups, PET cans, and high-performance sealing machines. We are committed to staying ahead of market trends through continuous R&D, delivering cost-effective yet premium-quality stylish packaging for global brands.
In the world of Double Seamer Machine manufacturing, the "Information Gain" lies in understanding the micro-parameters of the seam. While many suppliers offer machines, Copak offers Precision Control Systems.
Our machines and PET products meet rigorous FDA, CE, and ISO standards. We ensure that every component in contact with food is BPA-free and food-grade certified, providing peace of mind for exporters in the EU and North American markets.
With a technical team ready for global deployment, we offer remote diagnostic support and localized maintenance training. Our "Spare Parts Guarantee" ensures that your production line never stays idle for long.
We don't just sell machines; we provide the entire ecosystem. From custom printed PET cans to the seaming technology and the logistic support needed to get them to your doorstep efficiently.
